PLOW.

SPECIFICATION forming part of Letters Patent No. 368,527, dated August16, 18847.

Application filed March 4, 1887. Serial No. 229,704 (No model.)

To aZZ whom, it may concern.-

Be it known that I, LEWIs GIBBs, a citizen of the United States,andaresident of Canton, county of Stark, State of Ohio, have invented a newand useful Improvement in Plows, of which the followingis a full, clear,and exact description, reference being had to the accompanying drawings,making part of this specification.

My invention relates to improvements in plows; and it consists inproviding a plowbottom adapted to be used in the construction of plowsdiffering in size or material but of a similar conformation.

My invention also relates to and consists in providing aninterchangeable beam-standard and beam, and further relates to themanner of connecting the guide-wheel to the beam, and to all of thedetails and combinations of parts, as described, and set forth in theclaims.

Figure 1 is an isometrical view of a plow embodying my invention, showing the manner of using the wood beam. Fig. 2 is same view showing theuse of metal beam. Fig. 3 is a View of handle-socket. Fig. 4 is anisometrical view of the clamp by which the guidewheel is secured to thebeam. Fig. 5 is a view of a guide-wheel and supporting-shank, partlysectional, showing the thimble-skein and bolts. Fig. 6 is a View ofparts assembled for explanation.

Similar letters of reference indicate corresponding parts in all of thefigures in the ac companying drawings.

Letter A is a shoe of the form substantially as shown, having abackwardly projected wing, at, for a support for the lower end of thebeam-standard B, frame-piece C, and landside D, and an outwardly,backwardly, and downwardly projected wing, a, for a support for theshare E and mold-board E, the outline of which is indicated by thedotted lines, the mold-board being removed that the detail may be moreclearly shown. The landside D is bolted to and supported by theframe-piece G and the shoe A, the front upper edge of the landside flushwith the corresponding edge of the shoe. The share E is bolted to andsupported by the downwardly and outwardly projected wing a of the shoeA, the front edge of the share lapping over the front end of thelandside to a point about flush with the face of the landside, as shownin Figs. 1 and 2.

The frame-piece F, of the form substantially as shown in the drawings,Figs. 1 and 2, is a spreader or brace to support theshare and landside,and also a bottom support for the handles G and H, the lower end of thehandleH resting in asocket, K, said socket K being provided with a lug,of, by which it is bolted to the frame-piece F, and a lug, a (see Fig.3,) by which it is also bolted to frame-piece O, and the handle H issecured to the socket K by the use of a bolt, as shown. The handle G issupported and securedto the plow frame or bottom by the use of abracket, L, of the form substantially as shown, having at its lower enda flange, a, by which it is secured to the frame-piece F, and anupwardly-projected portion, (1 an outwardly and upwardly projectedportion, a, an inwardly-projected portion,a ,and an upwardly-projectedportion, (1 the handle being secured to the portions c and a,substantially as shown. That portion of the said bracket orhandlesupport designated a is slightly concaved, as shown, so as toconform to the convex or back portion of the mold-board.

In Fig. 2 there is shown attached to the metal beam M an outwardly andbackwardly projected bracket, a, as a support for the front upper edgeof the mold-board. The said mold-board when placed in position, as shownby the dotted lines, is bolted to the shoe by a bolt through theperforation b, to the bracket a by a bolt through perforation b and toframe F at b and to the concave portion a of the handle-supportingbracket by a bolt through perforation b, the front cutting-edge of themold-board overlapping the front edge of the landside and forming acontinuous cutting'edge from the point of the share to the top of themoldboard.

In the shank or shank-section of standard B of the metal beam M there isprovided a slot, 12 to receive a projected shank, b, on the bracket a",by which the said bracket may be o said shank B there is a socket, a, toreceive adjusted, and when so adjusted may be fixed by a through-bolt.Z) is a support for handle H,,having, as shown, one of its ends boltedto the beam, the other end bolted to the handle.

To adapt the plow to the use ofa wood beam, N, as shown in Fig. 1, thereis provideda castmetal standard, 13, having a flange, d, on its upperend,on which the beam rests,and flanges d d to strengthen said standard,and a central cylinder, (2 as shown, extending from the lower end of thestandard to the top and through which the beam'bolt (1* is passed. Bythis described form of a cast-metalstandard great strength is secured awith small amount of metal.

The lower end of the standard B is provided with a downwardlyandiorwardly projected end section, (I as shown by the dotted lines,said section having perforations d, and is otherwise adapted to bebolted to the shoe A. There is also provided and integral with saidstandard an outwardly and rearwardly projected lug, d, to which themold-board E may be bolted.

A beanrsupport, O, of substantially the form shown in Fig. 1, having avertical section, h,the lower portion of which is connected with thehandle G, a horizontal portion, h, connected with the handle H, and aslot, 71,2, and bolt k in the rear end of the beam N, as shown, may beadjusted to give theplow more or less land.

The guide-wheel support P (shown in Fig.-

4) is composed of two parts, 70 and k, the part 70 having a verticalannular socket, k", an inwardly-projected flange, is, having a slot, it;also from the upper end of said annular socket 70* there is aninwardly-projected flange, it having an upwardly-projected lug, it, saidlug having a perforation for clamping-bolt k7. Part is is formedsubstantially as shown in Fig. 4, having at its inner and lower end ahook, 768, adapted to enter into the slot is, the upper end having aing, it, perforated, as shown, for bolt If. The clamp formed asdescribed embraces the bean N, as shown in Fig. 1. Y

The wheel-shank R is adapted to and is adjustable in the annular slot 70and may be fixed by the setscrew u At the lower end of the thimble-skeina and asand-band, a The As hereinbefore stated, in the plow frame orbottom hereinbefore described, and consisting of the shoe A,frame-pieces F and O, the handle-supports L and R, with theinterchangeable beam-standards, is provided a frame for plows of two ormore sizes, only varying in the dimensions of parts, and may be used fora cast-iron or a steel plow, or for a plow composed of a compositionsteel and cast-iron parts, the parts being interchangeable, thus greatlyreducing the initial cost in manufacturing, as well as a greatconvenience to the parties using such implement.

Having thus fully described the nature and object of my invention, whatI claim, and desire to secure by Letters Patent, is-

1. In a plow, the combination, with the pl ow-beam and the plow'frame,ofa plow-standard consisting, essentially, of a hollow cylinder providedwith a flange at its upper end to form a seat for the plow-beam, a sideflange, as I), for the attachment of the mold-board, and aforwardly-projected flange, as (i at its lower end for the attachment ofthe plowframe, and a through-bolt, as (1*, for securing the standard tothe beam, substantially as set forth.

2. In a plow, a cast-metal standard, B, eonsisting, essentially, of ahollow vertical cylinder, d", top plate, (I, flanges (2 61 and adownwardly and forwardly projected section, (2 substantially as shown,and for the purpose set forth. 1

8. The combination, with a cross-brace, as F, of the plow-frame, of ahandle-brace, L, provided at its lower end with a laterallyturnedflange, as a", a seat for the lower end of the handle, as 811166 anoutwardly-curved portion, as a, forming an extended bearing for themold-board, and an inwardly-extend ing portion, as at, having a turnedflange for its attachment to the handle, the whole constructed andarranged substantially as set forth.

4. The handle-securing piece K, provided with a main portion adapted toreceive and embrace three sides of the handle at its lower end, with aperforated flange, a for its attachment to the cross-brace of theplow-frame, and with a flange, a, for its attachment to the frame-piecealong the landside, substantially as set forth.

In testimony whereof I have hereunto set my hand this 25th day ofFebruary, A. l). 1887.
